I once worked at a corp that sold software. For the exact same software product, maybe 10-20% of customers received so much benefit we could have charged 2-3x the price and they would still be very happy. On the other end, for maybe 10-30+%, the exact same product ranged from painful to a disaster. Often because they would try to force it to work the way their pre-existing paradigms worked instead of taking the time to learn how it actually worked.
